Saccharomyces boulardii may be beneficial to:
- Balance gastrointestinal flora
- Support immune function
- Support gastrointestinal barrier function
Saccharomyces boulardii is a health-promoting, probiotic yeast. It was first identified in the 1920s by French microbiologist Henri Boulard. Since its discovery, there have been 250 peer-reviewed articles examining S. boulardii, making this one of the most studied probiotics available. S. boulardii is a non-pathogenic yeast and is distinctly different from Saccharomyces cerevisiae, or "brewer’s yeast." S. boulardii has been shown to support gastrointestinal health by supporting secretory IgA (sIgA) levels. sIgA is an immunoglobulin that is found in the digestive tract and in mucosal secretions throughout the body. Maintaining healthy sIgA levels is crucial for supporting immune health, particularly in the gastrointestinal system. In addition to supporting sIgA levels, S. boulardii promotes gastrointestinal health by competing for space and nutrients.
